I also looked at using re.subst on $pU but can't get it to work.

What is the best way to achieve what I'm trying to do?

I would extract a substring based on length. Intermediate (first) variable 'pu_len' is required because transformations cannot be nested:

$var(pu_len) = $(pU{s.len}) - 1; $var(new_pi) = $(pU{s.substr,1,$var(pu_len)});

while this is correct, you can do it without computing the length: $var(new_pi) = $(pU{s.substr,1,0});

- meaning is that when len param for transformation is 0, get substring from position param till the end of pv value.
